Special Containment Procedures: As per Addendum XXXX-B, at least one phone with SCP-XXXX installed should be kept in a standard anomalous items locker for testing purposes.

All major smartphones application stores are to be actively monitored for instances of SCP-XXXX. Instances of SCP-XXXX are to be immediately removed from the store by embedded Foundation personnel.
Any subjects who have downloaded SCP-XXXX are to be tracked down and taken into Foundation custody.
Should the subject have turned into an instance of SCP-XXXX-1, facial reconstructive surgery is to be attempted if deemed possible. Amnestics are to be administered and a cover story to be given, such as a car accident or burn injury by fire.

If facial reconstruction is deemed impossible, instances of SCP-XXXX-1 are to be kept in individual standard humanoid containment cells and provided basic amenities. A limited selection of entertainment may be provided contingent on good behavior.

Description: SCP-XXXX is a smartphone application, periodically appearing on online application stores such as Apple’s App Store and the Google Play Store. SCP-XXXX appears under various display names, most commonly "Mr. Hubert's Wacky Camera Filters!" and "Crazy Fun Face Distortion for the whole Family". Other names using a similar format have also been observed.
As SCP-XXXX is affected by the built-in rating systems in the same manner as non-anomalous applications, exposure to larger amounts of subjects is considered unlikely as instances are able to be removed swiftly.

Although the manner in which SCP-XXXX appears on application stores appears to be anomalous and is currently not well understood, it can be downloaded in the same manner as a non-anomalous app. When downloaded onto a smartphone and launched, the application works similar to non-anomalous camera filter applications. The cell phone's camera can be aimed at human faces, which will then appear altered in some way on the screen. A variety of different “filters” are available.

The anomalous properties of SCP-XXXX go into effect when the face of a subject has been on-screen for approximately 10 seconds. After 10 seconds have passed the alterations seen on-screen will appear on the subjects physical face, turning them into an instance of SCP-XXXX-1.
Any extra body parts added in the physical alterations consists of living tissue and function as expected, but does not appear to greatly enhance any existing senses or grant the subject new ones.

For a list of examples of physical alterations in SCP-XXXX-1 instances, see Addendum-XXXX-A.

Facial reconstruction performed and amnestics administered and subject set free.

D-1395

Purple facial skin hue and rosy cheeks. A pair of butterfly-like antennae on top of head.

D-1395 kept unaltered for testing purposes and may be assigned ordinary D-class work.

SCP-XXXX was discovered when the Foundation was alerted to a hospital in San Jose, California. ████ █████, a ██-year old male, had downloaded SCP-XXXX onto his phone and triggered its anomalous effects, turning into an instance of SCP-XXXX-1.
████ █████, designated as SCP-XXXX-1-A, was taken into Foundation custody under the cover story of being taken to a more well equipped medical facility. Amnestics were administered to all civilians involved.

As there currently is no known method to reverse the symptoms shown by SCP-XXXX-1 instances without extensive reconstructive surgery, testing on D-class personnel has been approved as of ██/██/20██. At least one phone which has SCP-XXXX installed should be kept in a standard anomalous items locker for this purpose. - Dr. ███████
